5.4.3 NUMBYTES vs. Minimum / Maximum Jitter Values
Figure 5-2 shows graphically the minimum and maximum allowable jitter values for the NUMBYTES that are
passed in each packet.
FIGURE 5-2 Allowable Jitter Ranges
Table 5-1 correlates the data in a tabular format, with the following notes:
• Minimum jitter buffer depth - The user can specify any non-0 value, but the CSE8 card will select, at mini-
mum, a jitter buffer length of 2 packets (or the equivalent in microseconds) and round up to the nearest 250us.
• Maximum jitter buffer depth - There are limits on the number of packets that can be queued, as well as limits
on the total memory to queue the packets.
